IMPROVEMENT m' BuOYAn'r Puorrntnnna.

0- 1 The Schedule referred to in these Letters Patent and making part of the sama,

' buckets and the cylinder may be I illed with gas or cork,

Beit known that I, ELrsHA Mnrrnson, of Brooklyn, iin the county of Kings, and State of New IYork, have invented certain new and useful Improvements. in Method for Locomotion on Water, and .do hereby. declare that the following is a full, clear, and exact description'thei'ff, reference being had to theaceompanying drawings, and the letters of reference thereon, making a pait of this specification.

Figure 1 represents a plan view of my device;

Figure 2, a side'view; and l Figure 3, a side View of one ofthe prOpelling-wheels`, with broken lines, showing its construction.

. In the accompanying drawings, A represents the wheels, which are arranged in pairsin a suitable frame, B. These Wheels are supported upon suitable crossshaits, a, in said frame, which said shafts form a crank between er l rposite Wheel, as shown in fig. 1,.

.Each o heels A is made ofmetal, substantially' as. follows" I first form an air-tight cylinder, of suitaf, ble size, and arrange a series of V-shaped buckets or paddles, C, ,on the-outer periphery ofthe said cylin- O der. These v-shaped buckets are also air-tight, and

are independent of each other. The cylinder itself, as well as the buckets, is suitably braced on the inner side, as shown in fig. 3. Should oneof the buckets become broken oif, it willA readily be seen that no water can penetrate the other buckets or the cylinder A. These as preferred. .lhe Wheels A being placed in pairs, as shown in fig.

l, a connecting-rod is used upon the two (or merel crank-shafts, and the pitnian connected thereto. A 4 Any suitable kind of 'vessel mayl be added to the frame B and the air-tight wheels.

' .The peculiar' construction of these wheels buoys' the vessel, and, when steam-power is applied to' the pitman, causes the wheels to revolve with such rapidity` as to propel the vessel forward at a very great rate of speed. y

I am. aware that an air-tight wheel, with v-shaped buckets, formed with said wheel, is not new, nor their applvioationto a marine locomotive.

What I `clai1n, and desire to secln'e by Letters Pat ent, is The cylinder A, air-tight, and provided with independent air-tight Vshaped buckets, C, arranged On the exterior of said cylinder, and Within a'suitable frame, B, to operate substantially as set forth.

In testimony that I claimthe foregoing, I have here- I unto set my handkthis 7th day of August, 1 868.
